Canadiens 4, Senators 3 (SO)

MONTREAL -- Lars Eller scored the decisive goal in a shootout, and the Montreal Canadiens extended their winning streak to four with a 4-3 victory over the Ottawa Senators on Wednesday.

Montreal's Alex Galchenyuk also scored in the tiebreaker, and Carey Price stopped two of Ottawa's three shooters after making 29 saves during the game.

Montreal got two goals with the man advantage in the second period, as Brendan Gallagher and P.K. Subban put the Canadiens up 3-1. Eller scored in the first period.

Patrick Wiercioch drew Ottawa even at 3 with his third goal of the season 1:50 into the third. Mika Zibanejad and Daniel Alfredsson scored power-play goals for the Senators.

Robin Lehner made 42 saves in his third straight start for Ottawa, which has one win in its last seven games (1-3-3).

Galchenyuk fired a shot off the crossbar with 1:25 left in regulation after Eller stole the puck inside the Senators' blue line.

Alfredsson scored in the dying seconds of the middle period to draw Ottawa within 3-2. His shot over Price required a video review that showed that the puck struck the upper video camera inside the net with 1.6 seconds left.

Montreal's Gabriel Dumont got his first NHL point with an assist on Eller's goal 7:02 into the game.

Zibanejad drew Ottawa even at 1-1 with his sixth goal on a power play at 10:26 of the opening period.

Gallagher gave Montreal a 2-1 lead when he deflected Max Pacioretty's shot past Lehner for his eighth goal 6:40 into the second.

Subban made it a two-goal advantage when his drive from the point struck Ottawa defenseman Chris Phillips on its way past Lehner at 17:11 of the second.
